Description of key information

The n-octanol:water partition coefficient of 4-Oxo tempo (99.1% purity) was determined to be log 0.28 at 22°C and pH 7. 

Key value for chemical safety assessment

Log Kow (Log Pow):

Additional information

The octanol :water partition coefficient of a sample of 4 -Oxo Tempo was determined in an in-house study.

The study was conducted to the appropriate OECD guideline although not to GLP. Certain details are not included in the study report although this is considered not to affect the quality of the results. The study was assigned a reliability rating of 2 according to the criteria of Klimisch 1997.
